SCA: security update for org.http4s:http4s-server_2.12, org.http4s:http4s-server_2.13, org.http4s:http4s-server_3 (GHSA-crq5-92j2-j7wv)

medium Tenable Self-Hosted Container Security Plugin ID 447997

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Http4s is a Scala interface for HTTP services. Prior to 0.23.35 and 1.0.0-M47, ResourceService and
 WebjarService decode each URL path segment but reject only segments exactly equal to an empty string, a
 dot, or two dots. A request containing percent-encoded slash or backslash separators can turn an accepted
 segment into a parent-directory traversal after decoding, allowing access to classpath or WebJar resources
 outside the configured base when a directory-backed classpath is served and the backend preserves the
 encoded separator. The patch rejects decoded segments containing slash or backslash in ResourceService and
 WebjarService, and applies the same guard to the non-exploitable FileService for consistency. This issue
 is fixed in versions 0.23.35 and 1.0.0-M47. (CVE-2026-69201)

Solution

Update the org.http4s:http4s-server_2.12 library and its related packages to version 0.23.35 or later.
